CLEARVIEW — A driver crashed into an oncoming box truck on purpose, then ran from the wreck and claimed to have a bomb in his car Tuesday near Snohomish, according to state troopers.

State troopers shut down Highway 9 when the wrong-way driver rammed his Toyota car into a northbound box truck around 5 p.m. near 164th Street SE, said Washington State Patrol trooper Heather Axtman. Troopers suspect he crossed the center line on purpose.

The driver, 27, ran from the car, but the truck driver chased him and stopped him. The man claimed there was a bomb inside the Toyota.

So a bomb squad rushed to the scene. Traffic was detoured until the team could search the car. They found no bomb.

No one was seriously hurt in the crash, Axtman said. Both vehicles sustained serious damage.
